(Cl. 304-136) My invention relates to a scooper-attachment important, as calcimine or plaster scrapings do device, which is readily secured onto a scraping make a nasty mess. tool or knife, such as those used for scraping off Other features of my invention will appear as calcimine, and its purpose is to collect the scrapthe following description proceeds in the speci- 5 ings into a boX-likedevce as the knife cuts away cation, reference being made to the drawing, in 5 the calcimine, the device being dipped into water which for washing out the scrapings from the box-like Figure 1 is an exterior view of my scooper-dechamber, when the scooper is again ready for Vice, shown attached to a scraping tool or scraper. further scraping, and so on at intervals for a Figure 2 is a side or end View of Figure l.

These resilient members are held by a time and labor saving device, besides being a clamping strips 2| and rivets 22 to the side metal benefactor in cleanliness, whereby no scrapings walls I1 and I8, or in vany other suitable manare falling around on the oor, furniture coverner. An extension member or bracket 25 is se- ;5 ings, or the operator himself, and this is quite cured, such as by rivets |5c, to the bottom I 5 of 55 the box-like scooper S, and protrudes outwardly as shown in Figure 5, from the reduced end portion 26, of the scooper S, and is provided with adjustment holes 21 which may be a slot, through which a screw 28 is inserted and into the hole 29 of the handle 29 of the scraper or knife D, and a lock-washer 32 and lock-nut 33 tightly secures the screw 28 therewith. A dowel or anchor pin 34 is for the purpose of insuring the rigidity of the attaching arrangement, and the slotted hole 35 in the handle 29, is for the adjustment of the anchor or fulcrumed pin 34, when the scooper is set or pivotally adjusted in the holes or slot 21, due to the wearing of the cutting or scraping edge 3|a of the blade 3|, However, this anchor pin is optional, if other means is used.

A knob 45 is shown on the lock-nut 33, so in event of the inconvenience of having a Spanner or screw driver handy, the wing portion of the knob will produce means to loosen the lock-nut readily so the scraper D may be quickly reversed for the new cutting edge during a long continuous scraping job. It is quite essential the grip portion of the extention bracket 25 and handle 29 offers little obstruction, such as sharp corners or edges, and means to do this will be adopted, if so desired, such as to be described later. The end I6 and the blade 3| adjacent the cutting edge 3|a, provides an elongated opening 3|c through which the scrapings SC enter during the scraping operation.

It is to be noted that the blade 3| with a straight scraping edge is of a symmetrical type, that is, it is uniform so when it is reversed from one scraping position to another, it ts the same on the rubber cushioned side walls or seats. A scraping tool or knife having a slightly raised or pitched scraping edge may be used, if so desired, but if it is slightly oiset, my Semper-attachment will be made accordingly, but in this instance, the blade cannot be reversed, but is removed for sharpening the scraping edge. However, a pitched or beveled edge may be made for a symmetrical blade, in such an event, it may therefore be reversed.

In Figure 9, I show an all metallic scooperattachment SM, made of, for example, spring steel, or of any suitable anti-rust material, the end 60 being free from the integral resilient side Walls, slitted as shown at 60a, to have the same cushion effect for the blade 3| to depress itself thereon as the rubber walls I9 and 20, during the scraping operation.

In Figure 9a, a fragmentary view of one side of my scooper-attachment device is shown, provided with a solid rubber side wall R. in place of the looped cushions I9 and 20, or these resilent walls may be any similar material, if so desired.

In Figure 9b, the end IS' is shown part of the box-like member |561, with rubber sides (|9" and 20 not shown), which eliminates the adjusting means on the handle 29o of the scraping tool S as shown in Figures 1 to 3, to allow for the wearing away of the edge 3|a of the blade 3|. A bracket-clamping member 29hy and a screw 29e secures the box-like member |5a of this scooperattachment to the metal shank of the handle 29o. This upturned end I5 is shown beveled or obliqued, same as the end IE5 as hereintobefore described in the original scooper, so the operation of swishing or rinsing the scooper-device in a pail of water every three or four scrapings, will allow for the flushing the scrapings out of the scooper more so than if it was at a right angle or having square corner like. However, this beveled or cbliqued end must not be too much, as the scrapings may fall out during the scraping operations.

In Figure 9c, I show an alternative attaching means, in which the handle 29C is recessed out shown at 59, to receive a filler plate 5| and the bracket 25' of the scooper S, which is adjustable by the slot 52, and the screw which extends through the hole 56 in the handle 2SC, and is secured thereat in hole 511 of the ller plate 5|. These parts may be reversed from one side to the other, when the knife or scraper S is reversed.

It is understood I may adopt other means than shown in the drawing and hereinbefore described such as in the adjusting means, and the fastening or attaching means of box-like members to the handle of the scraper D, or in the rubber cushioning walls inbetween which interposes or abuts the blade 3|, which bends or depresses thereon, in

order to provide. a tight enclosed box-like cham,- ber for the scrapings, furthermore my scooper attachment may be also adaptable for use upon other similar work, wherever suitable, such as for example, on plaster and paint work, or any other similar work.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is as follows:

A scooper-attachment for a scraping knife, such as used upon calcimine work or the like, having a box-like member provided with resilient side walls, inbetween which interposes the flaring side edges of said scraping knife, such as a blade provided with a ared out cutting or a scraping edge, said resilient side walls being for the purpose of providing a tight scooping chamber between the box-like member and the scraping knife, when said cutting and scraping edge of the blade bends or depresses under pressure in its scraping operation.
